Quantum Nonlocality and Causation

    What, if anything, do the nonlocal correlations in the results of EPR experiments indicate with regards to causation? (That is, with regards to whether or not/how causation is [is not] operative in giving the resulting correlated measurements?)

    Causality is one thing and another the Nonlocality
    any event can affect two or more events set apart

    “It isn’t necessarily that something in region 2 is causally
    influencing something in region 1, or vice versa. It is
    always possible that there is some other event, neither
    in region 1 nor region 2, which was not determined by
    [λ], and which itself causally influences both [beables in
    region 1] and [in region 2]. The point is, though, that this
    causal influence would have to be non-local"

    and in the the overlap of the backward light cones of the events.
